Scientific preparations of archaeological ceramics status, value and long term future

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Patrick Sean QuinnThin sections, resin blocks, pressed pellets, fused beads, milled powders, solutions and digested residues are several key sample formats used in the invasive scientific analysis of ancient ceramics. They are crucial tools that enable researchers to characterise the mineralogical, geochemical, molecular and microstructural composition of pottery and other ceramic artefacts, in order to interpret their raw materials, manufacturing technology, production locations and functions. Despite the importance of such preparations, key issues about their status, such as whether they are still artefacts or not, who owns them and where they should reside after analysis, are rarely addressed in the archaeological or archaeometric literature. These questions have implications for the long-term future of thin sections, resin blocks and other sample formats, as well as their accessibility for future research. The present paper highlights the above problem and assess the roles, perspectives and needs of ceramic analysts, field archaeologists, commercial units, curators, policy makers, professional bodies, special interest groups and funding agencies. Finally, guidelines are put forward that can be taken into account when deciding on the value and research potential of scientific specimens of archaeological ceramics, as well as strategies for their curation.

A citation network analysis of lithic microwear research

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Christopher J. Dunmore, Ben Pateman, Alastair KeyThe introduction of lithic microwear research into the wider archaeological community by Keeley (1980) was concurrent with the development of the processual paradigm and the adoption of the scientific method. Subsequently, lithic microwear research has benefited from over 35 years of innovation, including the introduction of novel methodological and analytical procedures. The present study employs a citation network to objectively analyse the development of microwear research. Given developments in technology, as well as the institutional isolation of early microwear research, the present analysis considers the citation network that stems from Keeley’s seminal 1980 volume. The 363 papers identified as having cited Keeley (1980) in the subsequent 35 years were treated as individual nodes within the citation network. Before analysis, nodes were assigned attributes, including the type of research published and whether they were supportive of three key aspects of Keeley’s experimental program: the ability to determine the function of the tool and to ascertain the type of worked material from microwear, as well as the use of high-powered microscopy techniques. Emergent properties of the papers, including closeness centrality, indegree and betweenness centrality, are used to test for significant differences between paper attributes. Similarly a clustering algorithm is used to objectively define distinct clusters of important papers within the discipline. Results indicate that a small number of nodes in the network maintain statistically significant influence on the form of the citation network. These important nodes and the distinct ‘schools of thought’ identified are discussed in the context of Keeley’s initial contribution to the sub-field.

Breaking down the bullion. The compliance of bullion-currencies with official weight-systems in a case-study from the ancient Near East

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Nicola Ialongo, Agnese Vacca, Luca PeyronelIn this paper we provide an analytical insight on a specific form of bullion-currency. Through the comparison of the statistical properties of different samples of hacksilver and balance weights from various contexts of the Near Eastern Bronze Age, the study attempts to assess whether the weight values of bullion-currencies can be expected to comply with existing weight-standards. The results of the statistical analyses on a silver hoard from Ebla (Syria) strongly suggest that hacksilver in the Bronze Age Near East was shaped and/or fragmented in order to comply with the weight-systems that were in use in the trade networks where it circulated. The results also show the possibility to quantify the level of affinity between different weight-systems. The study is intended to provide a starting point for future research, aimed at the identification of different forms of bullion-currencies in pre- and protohistoric economies.

An insight into the burial practices of the late pre-Hispanic Los Amarillos community (northwestern Argentina) through the study of ancient DNA

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Fanny Mendisco, Christine Keyser, Veronica Seldes, Axel E. Nielsen, María Gabriela Russo, Eric Crubézy, Bertrand LudesA palaeogenetic analysis has been undertaken on the pre-Hispanic settlement of Los Amarillos (Regional Development Period, Jujuy Province, Argentina) to reconstruct kin relationship between individuals buried in two domestic areas. The aim of this study was first to genetically characterize the relationships between the individuals buried within the same funerary structure and, secondly, to correlate these genetic data with archaeo-anthropological data to discuss the burial practices and social organization of the Los Amarillos community. An analysis of both uniparental (mtDNA and Y-chromosome) and biparental (autosomal STRs) genetic markers was conducted on eighteen individuals recovered from three different burial structures. The very good DNA preservation contributed to characterize 13 mitochondrial haplotypes, 5 Y-chromosomal haplotypes and 11 complete autosomal STR profiles. The kinship analysis revealed that the domestic areas were used as family graves. Furthermore, they reveal that a maternal lineage is shared by a majority of the studied individuals from different sectors, suggesting matrilocal practices.

A new look at an old dog: Bonn-Oberkassel reconsidered

Posted on February 4, 2018 by ARCAS

Publication date: Available online 3 February 2018Source:Journal of Archaeological Science Author(s): Luc Janssens, Liane Giemsch, Ralf Schmitz, Martin Street, Stefan Van DongenThe Bonn-Oberkassel dog remains (Upper Pleistocene and 14223 +- 58 years old) have been reported more than 100 years ago. Recent re-examination revealed the tooth of another older and smaller dog, making this domestic dog burial not only the oldest known, but also the only one with remains of two dogs. This observation brings the total known Magdalenian dogs to nine.Domestication of dogs during the final Palaeolithic has important implications for understanding pre-Holocene hunter-gatherers. Most proposed hunter-gatherer motivations for domesticating dogs have been utilitarian. However, remains of the Bonn-Oberkassel dogs may offer another view.The Bonn-Oberkassel dog was a late juvenile when it was buried at approximately age 27–28 weeks, with two adult humans and grave goods. Oral cavity lesions indicate a gravely ill dog that likely suffered a morbillivirus (canine distemper) infection. A dental line of suggestive enamel hypoplasia appears at the 19-week developmental stage. Two additional enamel hypoplasia lines, on the canine only, document further disease episodes at weeks 21 and 23. Pathological changes also include severe periodontal disease that may have been facilitated by immunodeficiency.Since canine distemper has a three-week disease course with very high mortality, the dog must have been perniciously ill during the three disease bouts and between ages 19 and 23 weeks. Survival without intensive human assistance would have been unlikely. Before and during this period, the dog cannot have held any utilitarian use to humans.We suggest that at least some Late Pleistocene humans regarded dogs not just materialistically, but may have developed emotional and caring bonds for their dogs, as reflected by the survival of this dog, quite possibly through human care.

Experimental construction of hunter-gatherer residential features, mobility, and the costs of occupying “persistent places”

Posted on February 4, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Christopher Morgan, Dallin Webb, Kari Sprengeler, Marielle (Pedro) Black, Nicole GeorgeTemporal and caloric costs associated with building common hunter-gatherer residential features – housefloors, housepits, storage pits, rock rings, and various types of wickiups – are presented based on experimental construction of these types of features. For subsurface features, excavation rates and associated labor costs are consistent regardless of feature type, soil type, or feature size. Labor costs for surface features are largely dependent on feature size, complexity, and availability of raw materials. In total, the per-family costs of building a single-family hunter-gatherer residential base are just under one 8-h day and approximately 2500 kcal per person. Combined, these data indicate relatively low costs are associated with hunter-gatherer investments in persistent places and in residential facilities made from locally-available resources. Implied by the study is that initial use of a place might reduce the costs of and thus encourage subsequent reoccupations and that raw material availability may have played as much of a role in decisions about when to move as density and distribution of subsistence resources.
